Sunlight is a source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones, it helps maintain muscle strength in older adults, and it also plays an active role in a healthy immune response. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body's needs.

What is Vitamin D-3?Vitamin D-3 is an important hormone precursor that helps support bones, immunity, and cellular health.

What is vitamin D’s main function in the body?Its main function is to maintain normal levels of calcium and phosphorus in the blood. Muscles, and particularly the heart muscles, need a carefully regulated amount of calcium in order to carry out their work.

How does Vitamin D-3 work?Once it has been converted into its active form, Vitamin D-3 can enter cells and attach to specific receptors. It then controls the expression of genes that regulate the functions of many different tissues including white blood cells and and cells within the intestine. It also plays a role in regulating cell growth and bone density. Scientists believe that vitamin D affects the healthy expression of over 200 genes, more than many other single compounds.

Why should we be concerned about vitamin D?Researchers and health professionals report that suboptimal levels of vitamin D are widespread. Vitamin D is not available from many foods other than fatty fish or fortified dairy products. Alternately, it is made in the body when sunlight strikes the skin, but many people are concerned about too much sun exposure, or they use sunscreen or wear protective clothing, and as a result may get too little vitamin D.

How does vitamin D-3 impact immunity?The impact of vitamin D on immunity has become an active area of research, particularly regarding its influence on macrophages and all other white blood cells. Studies suggest that vitamin D appears to interact with many different cells within the immune system and can help support the immune system’s normal function of protecting the body.

Who will most benefit from supplementation with vitamin D?Vitamin D is an important immune health booster for young and old alike, both men and women. It is also of special value to older adults and to anyone who does not spend enough time in the sun or who has natural sunscreen because of darkly pigmented skin. Healthy bones, calcium absorption, and healthy cellular functioning are key vitamin D benefits appreciated by everyone. It comes in multiple forms and potencies to make it convenient for everyone to obtain their vitamin D requirements.

Additional Information

Source Naturals was created in 1982 by C.E.O Ira Goldberg to support each individual’s potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned - for the maintenance of well-being and the enhancement of life - simply didn't exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formula®, now the industry’s #1 immune support product.

Source Naturals’ comprehensive Bio-Aligned Formulas™ help bring the power of alignment to your body. When formulating, we evaluate the underlying causes of system imbalances, and then provide targeted nutrition to interdependent body systems.
